Summary about handheld laser welding machine

Compared with traditional arc welding, laser welding is easier and safer to handle for a beginner. The portable laser welder with compact machine size and simple welder structure but stable strength is convenient to use and has a long service life. Due to the concentrated laser spot, the powerful heat can melt and vaporize the target partial metal in a short time, leading to a firm welding joint without porosity. Keyhole and conduction limited welding are available by adjusting laser power. Also, the wobble laser head is developed to expand the welding seam width and tolerance range. Depending on the quick swing of the laser welder head, the size of the welding spot is equivalent to being doubled, enabling the larger gap variation in parts and put them together.

What is laser welding

The handheld fiber laser welder utilizes fusion welding to work on materials. Intense heat from the laser beam melts or vaporizes the partial metal, which then fuses with another metal as it cools and solidifies, forming a strong welding joint. With high power and focused energy, this machine enables fast welding and minimal heat affected areas. Its non-pressure welding method reduces damage to the workpiece. Additionally, concentrated heat reduces energy and welding material consumption, eliminating the need for electrodes and filler metals in most cases.
